Question #891

A hot air ballon (with bucket) has a mass of 900 kg. The balloon has a buoyant force upward of 12,000 N and a westward wind force of 500 N. Find the acceleration of the balloon. What is the force of gravity (weight) of the balloon and bucket?

Expert's answer

The force of gravity of the baloon with bucket is F = mg = 900 *10 = 9,000 N - downward.

Let's find the vector sum of all forces:

√ (12,000-9,000)

a = F/m = 3041[N]/900[kg] = 3.4 [m/sec

Let's find the vector sum of all forces:

√ (12,000-9,000)

^{2}+ 500^{2}= 3041 N.a = F/m = 3041[N]/900[kg] = 3.4 [m/sec
